PRESERVING-RECEPTACLE.

Specification of Letters Patent.

Patented Sept. 23, 1919.

Application filed May 31, 1916. Serial No. 100,937.

To all whom it may concern:

Be it known that I, HEIzo SHIGA, manufacturer, of No. 161 Oaza Shimo-Migita,

Migita-Mura, Saba Gun, Yamaguchi-Ken,

Empire of Japan, have invented certain new and useful Improvements in Preserving-Receptacles, of, which the following is a specification.

This invention comprises certain improvements in or relating to glass receptacles or bottles suitable for use in connection with the preservation of foods and the like, and has for its object to provide an improved, inexpensive, sanitary, simple construction for receptacles of thisxkind, particularly for the type where the opening and sealing of the mouth of the receptacle is accomplished in considerabl easier manner as compared with those whlch have been heretofore used or proposed, and further to provide an in1- proved construction whereby an outer lid or stopper will be utilized for and serve as an effective air tight cover even after the receptacle has been once opened without danger of spoiling the contents remaining in such opened receptacles.

My invention in its most desirable form consists in the combination of an inner and outer cover adapted to fit over the mouth of the receptacle having a series of'projections formed around the outer surface of the neck portion of the said receptacle, the characteristic feature being that the configuration of these projections has a substan tially wedge like formation adapted to engage with the corresponding series of looking members or catches formed upon the flanged portion of the said outer cover, a mere turning action of which outer cover aflords the means for sealing or opening the mouth of the receptacles, all as fully hereinafter described.

In the drawings, Figure 1 is a half sectional elevation of the glass bottle constructed in accordance with the present invention, illustrating the mouth in sealed condition.

Fig. 2 is a perspective view of the mouth of the bottle.

Fig. 3 is a perspective view of the outer cover tilted to show the lower surface thereof.

Fig. 4 is a modification.

Referring more particularly to the draw ing, the numeral 1 indicates glass receptacle of any convenient form and size, but essen tially stepped at its neck portion as shown at 3. 2 are the series of lugs or projectlons circumferentially arranged and equally spaced around the outer periphery of the said neck portion of the receptacle 1, preferably located below the step 3.

The configuration of these lugs 2 upon which the importance of the present invention resides is such that while forming its upper edge parallel to the plane of the circumferential edge of the mouth of the receptacle,its lower edge/ is substantially inclined or widened in breadth gradually downward so as to give more wedge like formation thereof, as shown in Fig. 2.

At 4 is indicated an inner cover which I form by bending a suitable sheet metal provided with a shoulder 5 so as to fit over the corresponding step 3 when the same is assembled over the mouth of the receptacle 1. 6 is, a suitable packing material, preferably of rubber, adapted to be placed between the lower surface of the said shoulder 5 and the upper surface of the step 3 in an air tight manner.

The outer cover 7 adapted to fit over the said inner cover 4 and which I form likewise by bending a suitable sheet of metal is provided at intervals with inwardly 'bent portions 8, formed by squeezing or pressing inwardly the flanged edge thereof, which, for the sake of convenience I term, hereinafter simply catches, being of the length equal to the distance between the said two adjacent lugs 2, that is to say, instead of assuming plain circular form the flanged edge of this particular cover 7 is broken at intervals by inwardly pressed portions 8, to the extent equal to the length corresponding to the distance between two ad acent lugs 2 as shown in Fig. 3.

The bottle, after receiving the contents to be preserved, is first covered over at the mouth with the inner cover 4 and subsequently cover 4 is covered over with the outer cover 7 in such a manner as to cause the said catches, 8 to engage partially with the corresponding lugs 2 to the extent just sufiicient to prevent the vibrating action of the covers 4, 7, while the air extracting operation is going on.

After the air has been extracted out of the receptacle, the outer cover 7 is fully turned until each lug 2 is fully enga ed by the respective catches 8. This will x the inner cover .4 rigidly in its position, and in view of the relative atmospheric pressure between the inside and outside of the recep tacle so that the inner cover 4 i kept pressed under all circumstances, thus fixing the mouth of the receptacle in a desired air tight manner.

Frequently, however, the inner cover 4 fails to be readily opened, due to adhesion resulting from the melting of the rubber packing 6. To avoid this difiiculty, I form as a modified arrangement an annular slit 9 circumferentially around the shouldered portion 5 of the inner cover 4 so as to take away or wind off this annular portion of the cover by means of the well known opener or key 10 as commonly used for opening any other preserving tin cans. In this case such key 10 may be conveniently placed upon the concave surface of the inner cover 4: as clearly shown in Fig. 4.

I-Ieretofore, owing to the complexity of construction, the packing operation has been often accompanied with several inconveniences, which defect I am enabled to overcome by my present invention.

Having thus described my invention, that I claim is The combination of a receptacle having a plurality of inclined external shoulders thereon, an inner cover for said receptacle having an annular shoulder adapted to clamp a gasket, and also having a cylindrical skirt below said shoulder fitting closely around the receptacle, said skirt being provided with a circumferential groove enabling said skirt to be wound off prior to the removal of the inner cover, and an outer cover having a skirt provided with inner bent spaced catches to engage said inclined shoulders of the receptacle, the skirt of the outer cover fitting closely around the skirt of the inner cover.

In testimony whereof I affix my signature in presence of two witnesses.

HEIZO SHIGA.
